The analysis of the influence of metal-containing additives of various chemical and granulometric composition (iron meerkat, FerroSAND – magnetite sand, aluminum powder and aluminum PA-4 powder) on the basic properties of sand-resin mixtures used for the manufacture of rods by the Cold box amin-process is presented. The influence of these additives on the strength of the mixtures in the cured state, on their gas content, gas permeability and crumbling was determined. The results obtained were compared with the characteristics of a reference mixture made without the use of additives.
Key words: Sand-resin mixtures, special additives, Cold box amin-process, tensile strength, gas content, gas permeability, casting defects, finning.
